Fix websocket error log handling

The commit b0ae71c[1] mishandles the error handling branches which
cause `operation_aborted` to be reported as an error.

```
            else if (ec != <error-cases>)
            {
                BMCWEB_LOG_ERROR("doRead error {}", ec);
            }
            else if (ec == boost::asio::error::operation_aborted)
            {
                BMCWEB_LOG_WARNING("doRead operation is aborted: {}", ec);
            }
```

This needs to handle `operation_aborted` first.

Tested:
- Unit test passes
